A blown fuse to what exactly and it should even though any fuses should be replaced as it goes to operate something signals etc . a bad bulb such as a head light needs replacing but has no effect on the charging system

Yes it will charge the battery unless the fuse that is blown is the one for the charging system. A blown bulb will not stop it from charging.

How to check alternater charging


start engine hold at 1500 rpm and disconnect battery if car stops the alternator not working .

Not charing


95 GC (this car the ENGINE PCM/ECU controls charge at all times.)
this year, the alternator is not a Standalone ALT> no internal reg.
my CHARGE lamp is on, is it? ah, Check battery above is not a verb its a lamp glowing. gotcha.
The system is called that a charging system
you connect any any voltmeter to the car battery
it must read 13.3 to 15v. running or the charge system is in failure mode.
top reasons,
1: bad batteries, yes, the Alternator reg, might just give up on a bad battery and just not attempt to charge it. so try that first. and the'
battery is the #1 failure on all cars...
corroded battery terminals or cable or alternator not grounded do to corrosion.
2: Fuse 6 or 8 blown in the PDC, both 60amp huge fuses.
3: bad wiring. bad connections to any of the alternators 5 connections.
5: the ASD relay can kill the ALT field current. as can the PCM.
6: bad ALT.
7: bad PCM.at pin C141.

i recommend (DIY) the FSM tests. or alldata.com .

there are test on car for each type failure.
id start with battery.

Chevy van g20 year 1994 the battery dies has new battery and new alternator but each morning its dead need to charge the battery need help have any ideas and please talk problem please


Does the battery light work when you switch the ignition on? This provides a live feed to the alternator via the ignition bulb, the rotor needs a live feed to start the charge process, if the bulb has blown it won't charge (thin wire connected to the IND on the alternator). To check for a power drain, disconnect the negative battery lead put a AMP meter in series, (DON'T TRY TO START, YOU WILL BLOW THE METER). If you get a reading above 0.05amps (clock) you have a drain, pull the fuses one at a time and watch for a drop in the meter reading. Hope this helps.

No charge voltage to battery. New alternator. No turn signals. This vehicle lost charging when towing trailer.


Troubleshoot by isolating the alternator, then testing for a 13.5 - 16v output (likely to be ~14.5v). Anything out of that range indicates bad alternator or voltage regulator (assumed to be built into the alternator). If voltage is in range, (and following your suspicion of an electrical problem in the Turn Signal circuit), reconnect the alternator and isolate the turn signal circuit by pull the fuses. See if you are getting the good voltage reading of (~14.5v) at the battery. IF IT'S GOOD..check for bad trailing wiring harness (isolate if possible), I've seen bad turn signal bulbs (contacts on bottom of bulb) short out (melt) in their sockets (typically causing a blown fuse..but ya'never know), and lastly you might have to do a hand over hand following the wiring, looking for shorts, melted wire, cuts, broken connections, etc (see Hanes Manual Wiring diagrams for possible points to perform continuity checks). IF IT'S BAD. you must continue to isolate electrical circuits until you find the one that is causing the fault. You can pull one fuse at a time (not reinstalling them) until voltage at the battery returns, or you might try pulling a group of fuses at a time until you can read good voltage at the battery, then replace the fuses one at a time until you find the bad circuit. Once you've isolated the bad circuit, it's either a matter of further isolation until you find the bad component (many circuits supply voltage to multiple components), or checking every connection and component connected in the circuit. Best of luck resolving this problem.

Alternator not charging battery alternator working battery not charging charge light on


check your wiring connections. if the problem persists check tto see if the car has a fuseable link.
it could be blown. its usually a ground or negative wire.

You should be able to to check for voltage directly at the the largest of the wires going to the alternator[black with an orange tracer].If you have no power then you have a blown fusible link,from the starter solenoid to the positive battery post.]If you have power then you either need a new rectifier put in the alternator or the charge lamp bulb is blown.

After replacing alternator, battery, headlights still do not work


if the battery was leaking acid from the filler caps on the battery it may have been caused by the alternator over charging (faulty voltage regulator) hence blow your light bulbs or blown the fuse check for blown fuses first,if they are OK you may have to replace the bulbs .....hope this helps....cheers

02 F250 7.3 battery light just came on, is this indicating a bad alternator or battery. Other than the light there are no symptoms so far


The light can be on because the charge or ALT fuse under the hood in the fuse/relay center is blown, or the alternator itself is not producing enough voltage.
